Check if window is using blastSync when deciding to use change tx

Even when blast sync is enabled, we still need to check if the window is
part of a sync transaction when deciding if it should use the change
transaction. If the window is not part of a sync transaction, we should
still apply the bounds change transaction directly. In the cases where
the window is part of a sync transaction, there will be no need for the
bounds change transaction since the buffer will be part of the sync
transaction

Test: PIP works with blast sync enabled
